Product Overview
The Subaru WRX STI Carbon Fibre Bonnet 2014-2021 transforms the front end of your WRX or STI instantly.
Genuine carbon fibre construction reduces bonnet weight by up to 50% compared to the factory steel unit. This directly lowers the centre of gravity, reduces nose weight, and sharpens the already excellent front-to-rear balance of the VA platform.
Whether you are building a track weapon in Sydney, a show WRX in Melbourne, a stage rally car in Brisbane, or a clean performance build in Perth — this is the bonnet upgrade your Subaru deserves.

Why the Subaru WRX STI Carbon Fibre Bonnet 2014-2021 is the Best Front-End Upgrade
Unlike fibreglass alternatives or heavy OEM steel replacements, the Subaru WRX STI Carbon Fibre Bonnet is constructed from genuine woven carbon fibre — the same material used in Formula 1, WRC rally cars, and premium supercar manufacturing.
Every panel line, vent, and mounting point is precision-moulded to match the exact factory bonnet dimensions of the 2014–2021 VA Subaru WRX and WRX STI.
The result is a direct bolt-on fit with zero modification — gap-free, flush, and factory-perfect from every angle.
Subaru WRX and STI owners across Sydney, Melbourne, Brisbane, and Perth consistently rate this carbon bonnet as the single most impactful front-end upgrade available for the VA platform.

The Subaru WRX STI Carbon Fibre Bonnet 2014-2021 delivers measurable performance improvements beyond aesthetics.

- Reduced Bonnet Lift: Improved airflow management reduces front-end lift at highway speeds
Why Carbon Fibre Beats Fibreglass and Steel

| Material | Weight | Strength | Finish | Best For |

| Factory Steel | Heavy | High | Painted | OEM replacement |

| Carbon Fibre | Lightest | Highest | Gloss carbon | Performance & show |

Engine Bay Cooling – How the Carbon Bonnet Helps Your WRX STI
Thermal Management on the VA Platform
The Subaru WRX STI Carbon Fibre Bonnet 2014-2021 features an integrated scoop design that actively manages engine bay temperatures.
During hard driving — track days at Sydney Motorsport Park, mountain runs in Melbourne’s Dandenong Ranges, canyon blasts in Brisbane’s hinterland, or summer highway cruising in Perth — under-bonnet temperatures in the EJ25 and FA20 engine bay can climb significantly.
The bonnet scoop works by:
- Extracting Hot Air: Pressurised hot air escapes through the scoop opening, drawing cooler air in through the front intake
- Reducing Heat Soak: Lower under-bonnet temperatures protect the intercooler, intake, and ancillary components
- Supporting Performance: Cooler intake air improves turbocharger efficiency and engine response
- Protecting Components: Reduced heat stress on wiring, hoses, and rubber extends component life
For track day preparation and engine bay cooling guides, visit NASIOC and IWSTI.
